IIS + PHP FastCGI Auto-Deploy#

A PowerShell script to automate the complete setup of IIS with PHP support via FastCGI on Windows 11 / Server.
Perfect for quickly deploying a PHP-based webmail (like Roundcube) or any PHP website with a custom domain.

Features#

• ✅ Automatic IIS installation – enables required Windows features (IIS-WebServerRole, IIS-CGI)

• ✅ Smart PHP download – detects the correct compiler version (vs16/vs17) based on PHP version

• ✅ Visual C++ Redistributable check – installs the latest VC++ 2015-2022 x64 if missing

• ✅ Idempotent – safe to run multiple times; skips already completed steps

• ✅ FastCGI configuration – registers PHP as a FastCGI application and adds the *.php handler

• ✅ IIS application pool & website creation – with customizable name, host header, port, and physical path

• ✅ Folder permissions – automatically grants read/execute access to IUSR

• ✅ Test page – creates a simple phpinfo() file to verify the setup

• ✅ Works with PowerShell 7.5+ – uses Windows PowerShell compatibility for IIS cmdlets
